Months later, Boston Marathon attack still felt across eastern Mass.

To mark the hundredth day since the Boston Marathon bombing – July 24 – and gauge how its impact still is unfolding today, Wicked Local and GateHouse Media newspapers are telling the stories of 100 people in eastern Massachusetts touched in some way by the violence.

The full impact of the Boston Marathon bombing cannot be told in a single story.

The attack killed three people and injured more than 260 others, and it also dealt a blow to hundreds, if not thousands, of other people: Friends and families of victims and survivors, spectators, emergency responders, medical workers, volunteers, runners.

Even more were affected by the manhunt for the suspects or played a part in the outpouring of goodwill and compassion for those hurt or killed in the attack.

To mark the hundredth day since the Boston Marathon bombing – July 24 – and gauge how its impact still is unfolding today, Wicked Local and GateHouse Media newspapers are telling the stories of 100 people in eastern Massachusetts touched in some way by the violence.

Only together do all these stories begin to paint a full picture of how the pair of explosions at the Copley Square finish line affected – and still affect – so many.

“100 Days, 100 Lives” found that for some, the wounds – whether physical, mental or emotional – still are painfully new.

“It will never be completely over, because she’s missed so much by all of us,” said Lillian Campbell, whose granddaughter, 29-year-old Krystle Campbell of Medford, was killed in the April 15 attack. “It’s just a big void in your life.”

The Somerville grandmother said her already tight-knit family has grown even closer and takes things one day at a time. She called her granddaughter “one in a million.”

Tsarnaev pleaded not guilty to 30 charges July 1 in his first appearance in U.S. District Court. If convicted, he could face life in prison or the death penalty.

Meanwhile, a number of survivors who lost limbs have taken first steps toward moving on with their lives on new metal and carbon-fiber legs.

Chris Martino, manager of United Prosthetics and Orthotics, said his business has worked with about half the 14 victims who lost one or both legs. At its Dorchester and Braintree offices, the business has crafted custom sockets for each patient’s prosthesis. Most include hydraulic knees for amputations above the joint, Martino said.

Survivors have been inundated with images of amputees who are athletes or otherwise had great success with prostheses, he said. Then finding that it can take months to learn to walk with a new limb can be a difficult adjustment.

“It’s doable for sure,” Martino stressed. “We do it all the time.”

Volunteers and fundraisers, meanwhile, continue their work. Red Cross of Eastern Massachusetts, for example, still is aiding 42 families in finding unfamiliar services, such as help making their homes wheelchair accessible, CEO Jarrett Barrios said. Red Cross also has focused on addressing mental health challenges people face in coping with an attack.

Many are determined to focus on the positive – volunteers who rushed into carnage to help the wounded, an outpouring of support for those hurt the most.

“Yes, I saw two people do a deed that was on the darkest side of humanity,” said Robert Wheeler, a runner captured in a now-famous photo at the finish line, holding his shirt to a wounded man’s elevated leg. “I also saw thousands of people do something that was on the brighter side of humanity – the brightest.”

Wheeler, 24, a Marshfield native and Ashland resident, is now in nearly daily contact with the man he helped, Ron Brassard of New Hampshire, and his wife and children.

“They’re family,” Wheeler said.

While what he witnessed at the bombing will always be with him, Wheeler said he is determined not to be overwhelmed by anger.

“There’s no way I’m going to let this mold me in a negative way,” he said.

One of the highest-profile sources of support for victims, One Fund Boston, distributed nearly $61 million to them and their families in late June.

“It worked, and it worked effectively and I think in a brilliant fashion,” fund administrator and attorney Ken Feinberg said recently.

The fund continues to accept new donations – it has raised more than $4 million since that initial payout – and local people continue to raise money for survivors facing lifelong medical bills.

How new contributions to the One Fund might be used is up for debate. The Massachusetts Bar Association has criticized Feinberg’s methodology for payments, based largely on length of hospital stays, for not weighing factors such as a victim’s age or an injury’s impact on his or her occupation.

The Bar does not want any money returned, but has asked Attorney General Martha Coakley to intervene going forward.

“Nobody got any money here that they did not deserve,” said Paul White, chairman of the Bar’s civil litigation section and a pro bono program for Marathon victims. “The question here is whether some people did not get money that they did deserve.”

Feinberg, who no longer runs the fund, said the criticism is well-intentioned, but said such considerations would have stalled aid to victims in need and added expense to the process.

“I think that speed, consistency and cost trump the theoretical concerns advanced by the Mass. Bar, which in principle I can’t argue with,” Feinberg said.

Page 3 of 3 - Runners, meanwhile, have begun looking to next year’s Boston Marathon. Wheeler, who has run at least two marathons since Boston, said he has seen other races more packed than ever. He plans to run Boston next year, too.

He recalled grabbing a cup of water for a runner who struggled up Heartbreak Hill before the bombing in April. Later, she caught up to him as he tried to stretch out a locked knee and encouraged him to finish the race.

“That’s the community of runners that I think will grow with what happened,” Wheeler said. “I’ve already seen it grow.”
